I went to all the stores in my area and none of them sell the 2.5A Micro USB charger I need to get this thing enough power. Does anyone else on here have any issues connecting when their Pi isn't getting enough juice? It was totally fine for me a month ago.
Is my lack of enough power the issue or is my lvi dead? This is giving me a headache.
You don't actually need a 2.5A charger for the DreamPi. 2.5A charger is required when you overclock your Pi, in your case you can settle with a lower amperage. I use an nVidia Shield charger, with a hi-quality 2A cable for my overclocked RasPI3B, and it works like a charm (even on high load, as I also use it for RetroPie and heavy stuff, like Quake in DosBox. When I used a lousy phone charger it displayed the undervoltage warning, and the thing was stuttering and dropping frames like crazy). For an untouched Pi a >1.5A will be enough.
One of the things to remember, while getting a power supply for the Pi, is a solid micro USB cable. Even with the best charger around, when the micro USB cable is lousy frequent undervoltages will occur, and the Pi is going to have performance problems. And yes, the cable will wear over time, so you might want to replace it from time to time.
As for the LVI cable, like pcwzrd13 wrote, you need to check the voltage to be sure.
